研究方向

The issue requests that Terser remove constructors that only call super(...arguments). Investigate the compress/classes.js or compress/drop unused.js pass to see where class constructors are handled. Look for existing logic that removes empty functions and extend it to detect constructors that do nothing but delegate to super with spread arguments. Consider edge cases where the constructor may have side effects (e.g., if super is called with non spread arguments).
